I have an opportunity to get a Trace BLX-80 1x12 (or was it 1x10? Since I will often run an extension cab with it, it makes little difference to me.) combo for $275. For those not familiar, the BLX-80 has a subwoofer-style cabinet with just a front vent; the speaker may be rear- or down-firing, I'm not quite sure. Should I grab it? A small combo would probably be more useful to me than a small head.
